Through physiological adaptations, mangroves are able to live in harsh saline environments. Red mangroves occur where soil salinities range from 60-65 parts per thousand (ppt) while … WebRoots, stems, and leaves respire at rates much lower than are characteristic of animals. Only during photosynthesis are large volumes of gases exchanged, and each leaf is well adapted to take care of its own needs. The distance that gases must diffuse in even a large plant is not great. Each living cell in the plant is located close to the surface.

WebSecondly, capillaries also reduce the diffusion pathway by being situated in areas where exchange tissues are found, e.g. alveoli in the lungs, and thus this increases exchange efficiency. Finally, capillaries are also arranged in networks known as capillary beds, and thus multiple capillaries are spread over a large area. WebAdaptations of the whole leaf for gas exchange.
